Emmersberg tunnel

from Wikipedia, the free encyclopedia

The Emmersberg tunnel is a 761 m long railway tunnel . It is located under the city of Schaffhausen in Switzerland on the Schaffhausen – Etzwilen railway line, today's lake line .

The tunnel leads from the portal near the Schaffhausen train station in a right curve in a south-easterly direction to the Rhine. Immediately afterwards the 262 m long Rhine bridge Feuerthalen follows .

history

The construction of the railway line between Etzwilen and Feuerthalen was decided in 1870, the opening by the Schweizerische Nordostbahn (NOB) was on November 1st, 1894. The section between Feuerthalen and Schaffhausen was put into operation on April 2nd, 1895 after the Emmersberg tunnel and the Rhine bridge had been completed .

Construction of the Emmersberg Tunnel began in 1893. The work was delayed until 1895 due to water ingress and a break in the river. To overcome the problems, a new method was used: with the help of a compressor and a pressure lock, an overpressure was built up in the tunnel to counteract the water and sand ingress. The breakthrough took place on December 13, 1894, and commissioning took place just four months later.

In summer 2004 the tunnel was extensively renovated. The track was also lowered a little bit in order to obtain the clearance profile required for double-decker trains .
